蹄病奶牛血液与尿液部分指标的检测及病因分析

Some Blood and Urine Pathological Examinations and Aetiological Analysis in Dairy Cows with Laminitis

针对广西某奶牛场蹄病发病率高的现状，选择34例蹄病奶牛采集其尿液和血液，应用尿常规快速自动分析仪对部分尿液指标和血浆钙、磷水平进行检测与分析。结果表明：尿糖、尿胆红素呈阴性，尿血微量，尿比重、尿pH、尿酮异常者占23．5％（8例），尿蛋白呈阳性者占35．2％（12例）；血浆钙平均值为8．3mg／dl，低于正常参考值（9～12mg／dl）的下限；血浆磷平均值为6．8mg／dl．高于正常参考值（4～6mg／dl）的上限。经过综合分析，认为本病例的发生与亚急性瘤胃酸中毒有关。

In order to investigate the etiology of hoof disease which occurred in high morbidity in one of Guangxi dairy farms, blood and urine salnples were collected from 34 cows with hoof disease, blood plasma calcium and phosphorus concentrations was determined by conventional metbods and some urine analysis was conducted by urine routine automatic analysis instrument. The results showed that glucose and bilirubin in the urine were negative, urine blood appeared minimum. 23.55% of cows examined displayed abnormal in specific gravity, PH and kelone bodies of urine. 35.2% of cows examined displayed positive in urine protein. The results of blood examination showed blood plasma calcium and phosphorus average concentrations were 8. 3 mg/dl （normal：9-12 mg/dl）and 6. 8 mg/dl（normal：4-6 mg/dl）,respectively. It is considered that the development of cow＇s hoof disease in this farm was associated with subacute ruminal acidosis after combination of all informations.
